-/**
- * Handling of bibtex fields.
- * All bibtex-field related stuff should be placed here!
- * Because we can export this information into additional
- * config files -> simple extension and definition of new fields
- *
- * TODO:
- * - handling of identically fields with different names (https://github.com/JabRef/jabref/issues/521)
- * e.g. LCCN = lib-congress, journaltitle = journal
- * - group id for each fields, e.g. standard, jurabib, bio, ...
- * - add a additional properties functionality into the BibField class
